Alwaght-At least 84 people have been killed in France after a truck careered along Nice's packed waterfront on Thursday.
Video footage shows police trying to stop the lorry before it picks up speed, slamming into revelers gathered along the city's famous waterside Promenade des Anglais for a Bastille Day fireworks display.
Following the attack, French President François Hollande announced that he would extend his country’s state of emergency — due to end July 26 — by an additional three months.
The emergency measures have been in place since the terror attacks on Paris in November last year,
Hollande condemned the attack as a “monstrosity,” and said there could be no doubt that it was an act of terror.
Speaking later on Friday,Hollande said nearly 50 people are in a critical condition following the deadly terror attack.
"As I speak 84 people are dead, and around 50 are in a critical condition between life and death," Hollande said in a speech from a hospital in Nice .
The French president said many foreigners and young children were among the casualties.
He said that operational reserves had been called up to aid police and security forces, particularly in border areas.
The attacker has been identified as a 31-year-old Franco-Tunisian Mohamed Lahouaiej-Bouhlel with police saying investigations are underway to find out the motives behind the attack and if there were any possible accomplices.
Meanwhile a cousin of Mohamed Lahouaiej Bouhlel’s wife says the Nice killer was a “nasty piece of work” who beat his wife and was “not a Muslim”.
Walid Hamou, a cousin of Nice suspect Bouhlel’s wife Hajer Khalfallah, told MailOnline: “Bouhlel was not religious. He did not go to the mosque, he did not pray, he did not observe Ramadan.”
“He drank alcohol, ate pork and took drugs. This is all forbidden under Islam,” he said.
“He was not a Muslim, he was a s---. He beat his wife, my cousin, he was a nasty piece of work.”
The Paris prosecutor's has office opened an investigation for "murder, attempted murder in an organised group linked to a terrorist enterprise". The probe is being handled by France's intelligence agency and judicial police.
